Pro Mariner 23122 ProIsoCharge 180 Amp 12V Battery Isolator

The Pro Mariner ProIsoCharge 23122 is an intelligent 180 amp battery isolator that revolutionizes onboard charging with digitally controlled alternator output distribution. Unlike traditional diode-based isolators that lose 0.6VDC, this advanced system delivers zero voltage loss isolation while protecting your engine start batteries and charging up to 2 additional battery banks from a single alternator.

Key Features:

• Digital Zero Voltage Loss: ProMar Digital Performance technology eliminates the typical 0.6VDC loss found in traditional isolators, ensuring faster charge times and fully charged batteries
• Intelligent Priority Charging: Automatically prioritizes charging to battery banks under load (house bank or inverter bank) while taking fully charged batteries offline and maintaining engine battery health
• Real-Time LED Status: Highly visible LEDs indicate alternator power presence, battery bank charging status, and fault conditions including high/low alternator output, over-voltage protection, and high voltage detection
• Ignition Controlled: Distributed On Demand battery bank management activates only when ignition power is on
• Advanced Regulator Ready: Includes remote sense connection for precision alternator algorithm control on alternators equipped with advanced regulators
• Modular Installation: Easy installation with included terminal stud insulator boots and protective snap-on safety cover
• Marine-Grade Protection: Ignition protected and waterproof to IP66 standards

Specifications:

• System Voltage: 12V DC
• Maximum Current: 180 Amps
• Alternator Inputs: 1
• Battery Outputs: 2
• Dimensions: 6.15" L x 5.875" W x 3.125" H
• Weight: 3 lbs

When paired with Pro Mariner's ProNautic P Series chargers, boat owners can maximize both shore power and on-the-water charging performance. The all-in-one design eliminates the need for multiple voltage sensitive relays, saving installation time, space, and cost while ensuring optimal battery health across all systems.
